Abstract of the Disclosure A combination otoscope and audiometer provided with conventional lighting means and an unobstructed viewing passage for visually inspecting the ear canal of a patient. The hand held instrument is also provided with a calibrated electronic circuit that automatically produces a sequence of tones of different frequencies and intensities, together with means for transmitting these tones to the patient's ear. The circuit includes timing means for precisely controlling the duration of each tone. Neither the production of the tones nor the duration thereof is under the control of the operator. The exterior of the instrument is provided with indicators in the form of light emitting diodes to tell the operator when each tone is being transmitted to the patient's ear.
